Multi-Mode Optical Attenuator Built-In Power Monitoring Accuracy
The optical attenuation and optical power output can be set quickly
and accurately, and the optical power attenuation stabilization
time is less than 200 ms.
Multi-channel attenuator is set at the same time, and multiple
ports are measured simultaneously, which saves a lot of measurement
time;
Built-in power monitoring ensures the stability and accuracy of
light attenuation;
Simple operation, intuitive graphical user interface, multi-channel
data preview, test status at a glance.
Small size, compact structure.
A multi-mode optical attenuator is a device used to reduce the
intensity of the optical signal in a multimode fiber. It is often
used to adjust the power of the optical signal to maintain the
stability of the system, or to provide repeatable results during
testing and measurement. Multimode optical attenuators can be
implemented in a number of ways, including using effects such as
light absorption, scattering, or interference.
